Index in cosmos db

As stated in Index Types Azure Cosmos containers support a new index layout that no longer uses the Hash index kind. If you specify a Hash index kind on the indexing policy, the CRUD requests on the container will silently ignore the index kind and the response from the container only contains the Range index kind. With Cosmos DB, you do not need to deal with schema or index management. The database engine is fully schema-agnostic. Since no schema and index management is required, you also don’t have to worry about application downtime while migrating schemas. Cosmos DB automatically indexes all data and serves queries fast.

The Cosmos DB engine is not bad at searching through vast swathes of JSON data. If you need to use a wildcard search for a text inside a specific attribute, the CONTAINS() function is a good starting point. You use it rather like a T-SQL LIKE in a WHERE clause. NOTE: Load the SimpleCars2 data into the Cosmos DB emulator. For help with this, see

17 Feb 2019 By default, the Azure Cosmos DB data is indexed. Azure applies its default indexing policy while creating a collection. However, a user can set 

Cosmos DB automatically indexes the documents, and this helps the high throughput of these query in most cases. But, you remember that not all the query is covered by the default index settings, and the index designing is still important for detailed cases. Here I explain how it works and how to design. By default, every field in each item is automatically indexed, generally providing good performance without tuning to specific query patterns. These defaults can be modified by setting an indexing policy which can specify, for each field, the index type and precision desired. Cosmos DB offers two types of indexes: In the Cosmos DB documentation I found this cenario and the suggestion is increase RU. Currently I have 400 RU/s, when I increase to 10.000 RU/s I'm capable to run the command with no errors but in 5 seconds. I already tryed to create index explicity, but it seems Cosmos DB doesn't use the index to make count. Range and hash index types are ignored by the Cosmos resource provider now for new containers or containers that were created within the past year or so. ARM does not validate the index policy which is why the template will deploy successfully. Azure Cosmos DB Graph: How to run queries in Graph API when Indexing Policy is defined as Manual? 0.

At this moment it is not possible to create unique indexes on a field in a collection (which is not a primary key). Through the Mongo Db driver, I can use the "CreateIndex" method without any problem, it returns "Ok", but the index never appears in MongoChef or RoboMongo to be applied on the collection. It would be nice to have unique index capacities in MongoDb through Azure Cosmos Db
